chronic mesenteric ischaemia
chronic mesenteric ischaemiaA condition characterised by intermittent severe ischaemia resulting in abdominal colic, beginning 15–30 minutes post-prandially and lasting 1-2 hours, which appears when 2 or all 3 of the superior and inferior mesenteric and coeliac major abdominal arteries have severe atherosclerosis. Because the intestine’s O2 demand increases with meals, patients may avoid the pain by not eating, thus losing weight. Malabsorption may occur because absorption is O2-dependent.
Popularly known as abdominal angina, chronic mesenteric ischaemia is preferred by journals that use British English, while chronic intestinal ischemia is used in journals that publish in American English.
